Body only. No operational issues. This model extracts the popular drop-tune function from the Whammy DT into a compact pedal size. It allows for down-tuning up to a maximum of one octave in half-step increments without changing the tuning of the guitar itself. Equipped with a momentary on/off switch, it allows you to instantly play just one phrase during a performance in down-tuning. Price is firm and non-negotiable.
